My invention relates to apparatus for fill ing receptacles with liquid and an object is to provide for automatically stopping the flow of liquid when the level of liquid in SI the receptacle being filled reaches the de sired height, thereby preventing overflow. Another object is to provide a device of this character by means of which comparatively small receptacles'may be readily filled from a comparatively large supply receptacle. An example ofthe use of my apparatus is in filling lamps from a can containing a supply of oil suificient for filling a plurality of lamps or for filling a lamp a plurality of times. It will be understood, however, that the apparatus may be employed for use with other liquids besides oil. I accomplish the objects of my invention by providing a combination which includes a supply receptacle, a well below the supply receptacle with which the lower end of the latter is connectetl, an air tube leading into the well, a delivery pipe leading from the well with its outer portion turned downwardly and adapted to extend into the top of the receptacle to be filled whereby the flow of liquid into this receptacle will be automatically stopped when the level therein reaches the level of the lower end of the air tube or the level of the air inlet to the liquid of the supply receptacle, and a. manual shutoff device which is closed before the filled receptacle is removed. r

The full. objects and advantages of my invention will appear in connection with the detailed description thereof, and then ovel features of my inventive idea will be particularly pointed out in the claims. 7

Fig. 18 is'a fragmentary view showing the application of a stop device/ Referring first to the constructionshown in Figs. 1 and 2, the numeral-14 designates a. supply receptacle which maybe an oil can placed in inverted position and shown as provided with a bail attachment'lfi. The receptacle 14 has a neck portion '18.which rests upon a rubber ring 20 carried by a dished member 22 which is supported by a stand24. .A well '26 extends down from the member 22 while the bottom ofthis well has secured thereto an upwardly extending post or abutment 28. When the supply receptacle 14 is placed in position, a valve stem 30 strikes the abutment 28 so that a valve 32 carried by the stem islifted from its seat 34 whichis formed in the upper side of a hollow memabove the bottom thereof. In the embodiment as shown in Fig. 1, the tube44 conall) at its upper end is provided with an enlarged chamber 46 furnished with a screw cap 48 containing perforations 50 so that when this cap is partly unscrewed, the tube 44: is opened to air. The purpose or" the enlargement 46 is to prevent overflow of the liquid in case some of the liquid should he forced up the tube when :the device :stands .in a warm room. A horizontal tube 52 leads fromthe well 26 at a place near the top thereof and the outer end of this tube is connected with a downturned portion 54: whose lower end is disposed at a lower level than the'lower end of the airtube 44 and is adapted to be closed by a shutoff valve 56. This valve is secured to a stem 58 whose upper-end is looped around the router reduced end of a leaf spring as will be IlIIClEl'SllOOl from Fig. 2. The inner :end of the spring 60 has a downwardly and 'ba'ckwardly bent portion '62 which is secured to the tube 52 *by bolting, soldering or welding. The tension of the spring 60 normally holds-the valve 56 ClOSQClifll'lCl in order to hold the'stem :58 in place, the outer portion of the spring 60 lies in engagement with :a pin 64; while at the other side of :the looped end of the stem i5t8, the spring 60 is provided with :a downwardly bent portion 66. In'o'rder to open the "valve 56 whenever desired, the spring L60 at :an intermediate portion thereof .is straddled 'by the notched end of an upwardly-extending rod 68 whose upper end is iiormed into a ball which is received in 'a access inthe lower end of a screw belt 370. This bolt has screw threaded engagement with the interior of a tubular extension 72 ten-tending up from the tube 52,the upper end of this extension :being closed by a packing gland 74. The supply receptacle is placed in the position shown in .Fig. 1 with the valve 556 :closed. A lamp bowl 76 or otherrecepta- :cle tobe filled is placed with its neck extendring up @outside of the lower end of the tube :54, itrbeingunderstood that the neck is larger 7 the tuberso that air can readily escape trom the receptacle E6. Upon opening the slntt off'valve 5.6 liquid starts to flow through the tubes :52 and '5 liinto the receiving receptacle 6. Thecap l8 beingin open position passes :down @the :air asupply tube'dl and bubbles up into the supply receptacle 14,

:thereby breaking :the vacuum which tends to :Eorm at the upper portion thereof. .Itwill be understood .asa :matter of course that if liquid has :been forced up the tube 44: ion ac- :count of the :devicestanding ma. warm room, the liquid in the tube ll will immediately flow out assoon =as thefiow through the tube 52.-sta*rted. Therefore when the 'filling'operati'on -is taking place, there is no "liquid in the tube 4d. Liquid will continue to flow into "the receptacle 76 until the level therein reaches the level of the lower end of the tube 44. 'Thereupon a balanced condition occurs .siniilarito that'existing'inso=called fountain *-thr.eaded extension on the tube 841.

by a valve 32similar to that previously de-t scribed and adapted to be held open by a post 28secured to the bottom of a well 78. This well corresponds in .a :general way to the well 26 shown in Fig.1, but there is .an .-air tube 80 leading .to the upper-,par tof. the

well. .Tnrthermerefla delivery tube 82 leads out of the lower portion -ozf. the well instead of out of the upper portion thereof. The itube82 extenclsaipwardly in inclined position and Emerges into a horizontal tubular member 8st and the latter is connected to a downturned ,member .86. Connected with the tubular member =8land positioned above the same, there is a chamber .88 having a tubular extension containing perforations -92.- The extension 90 is internally threadedi to receiye -.a .screw plug 9a which when partly imscrewed allows iair'to pass out-of the perforation-s .92. A sleeve member .96 slidably surrounds the tubular member .86. The

l-owerendpf1the;sleeve"96 is provided withUl .a shutoff aralve 98a-bove which are perforationslOO in the sleeve. The upperxend \of the sleeve 96 is provided with a disk 102 having a central threaded opening which is rotatably held a cap 106 secured to a The imember33 has openings 109 through which air may pass upwardly. In first starting this iormcf the device, the screwplug Ql-isl partly unscrewed so that air can escape from the tubular members '82, 84, and 86 and from the chamber 88. Liquid is poured into the well 'ZSand when it reaches the level of \the highest-part of the chamber-88, the air in the ,iiaucet and chamber 88 will have been completely driven -.out. The screw plug 9% is then ttmneddown and .the faucet isopened to draw elf liquid from the dished member .22 and well 78 until no more runs out. The device is now ready i501 filling of small receptacles. The supply receptacle 1% is put position :as :shown, and a receiving receptacle 108 is placed with its neck extending 'up outside the slower end-of the sleeve 96,'the neck larger *t'hant'he lower-end of'the sleeve so ithatai-r in the receptacle 108 can readily escape. hen the receptacle 108 is filled, liquid will stop flowing into this re ceptaclesincesa balanced condition will now engaged by a screw 104: whose lower end vE1305 exist. The operator closes thevalve 98 before removing the receptacle 108: and the apparatus is'in condition for another filling operation, since the liquidwill again start to flow upon opening the valve 98'. It will be understood from Fig. 3 that the liquid. is taken from below the lower end of the air inlet, but is raised above the same and passes on down so that the flow into the smaller receptacle is stopped at the level of the air inlet to the supplyreceptacle 14. i I

In the form of invention shown in Figs..7 to 13, thereisa supply receptacle 110 from the lower portion of which a tube 112- extends out horizontally and leads into a downturned member 114. A cylindrical extension 116 projects upwardly from the junction of the tubular members 112 and 114, this extension and the tubular member 114 being surround The lower endof the sleeve 118 is provided with a shutoff valve 120 above which are perforations v122.

ed by a slidable sleeve 118.

The upper end of the sleeve 118 is provided with a disk 124 having a central threaded a; opening which is engaged by a screw 126.

A conical member 128 is secured to the lower end of the screw 126. A strip 130 is secured by a screw 132 so as to project up from the member 116. The upper end-of the strip 130 is bent over at right angles to form a member 134 which is inwardly spaced from the sleeve 118 as shown in Fig. 11 so as to permit passage of air. The screw 126 passes loosely through the member 134. The upper end of the member 116 is providedwitha conical seat 136 adapted to receive the conical memher 128. The seat 136 extends into a bore 138 from which an air tube 140 extends horizontally and then has a downwardly bent member 142 which extends down nearly to .the bottom of a well 144 with which the tube 112 is provided. From an inspection of Fig. 7,

it will be understood that when the screw 126 is turned downwardly, the conical memside the lowerend of the sleeve 118, the neck being larger than the sleeve so that air in the receptacle can readily escape. The screw 126 is then turned in the opposite direction from that previously referred to so as to open the air tube. When the conical member 128 reaches the member 134, the valve 120 will be moved into open position as shown in Fig.7. Liquid now flows into the receptacle 146 while air passes down the tube 142 and up into the upper portion of the supply receptacle 110 to break the vacuumwhich tends to form therein. In order, that air may readily pass up into the receptacle 110, a curved member 147 is placed in .*the-. bottom of the tubular member 112 between the receptacle 11 0 and the air tube 142 so asto form a passageway tor air as'will be understood from Fig. 9. The liquid will stop flowinginto the receptacle 146 when the'leveltherein reaches the level of the lower end of the tube 142. since a balance condition then exists in the manner previously stated. The operator closes the valve 120 before removingthe filled receptacle. Fig. 8 shows the slidable sleeve 118 provided with graduations 148,the zero mark being at the same level as. the lower endof the tube 142' when the sleeve is inlowered position. If a receptacle having no neck is to be completely filled, the top'of such re ceptacle will be placed at. theheight of the Zero mark. If a receptacle having no neck is to. be filled. except for the neck, then the top of the neck will be placed on a level with the graduation corresponding to the length of the neck. Fig. 12-shows an attachment for use when it is not desired to automatically stop the flow of liquid. ,In such case, the sleeve 118 does not extend down into the receptacle to be filled. Therefore, in order to direct the flow of liquid which comes outof the lateral perforations 122,a globular member 150 is secured to the lower end of the sleeve by set screws 152, the member 150 having an open lower end portion 154'which directs the liquid downwardly. Fig 13 shows a. slight modification in regard to the well construction. In place of the well 144 as before, a well 144 is provided having a vertical partition 156 near the inner wall thereof stopping short of the bottom. The air tube 142 leads into-the top of the space out 011 by the partition 156. p A horizontal place of the curved partition 157 takes the, member 147. i

In the form ofinvention shown in Figs. 14 to 18, there is a supply receptacle 158 from the lower portion of which atube 160 extends out horizontally andleads into a downturned member 162 which has an upper portion which is screwthreaded both internally and externally. The external'threads serve for attachment of a packing gland 164. The in- .ternalthreads are. engagedby threads on a rotatable rod 166 which carries a stem 168 attachedto thelower end of which is a shutofi' valve 170 adapted to cooperate with a. valve" seat onthe lower end of the tube 162. well 17 2 extends down from the tube 160. Above the well 172there is an upward, hollow "extension 174 provided with a tapered plug valve 176 having a handle-178 by which it may be rotated. Theplug is held in place for rotative movement only, by a screw cap 180. The extension 174 is provided with a perforation 182 with which a passageway 184 in the valve may be made to register.

From the passageway 184, an air tube 186 extends down nearly to the bottom of the well stacle .190 while air :passes down the tube 1186' and up into the 'upperportion .ot the supply Dreceptacle 158 to break the vacuum which :t811Cl-S't02f0l111 therein. The liquid will stop .flowin'g into the receptacle .190 when'the level therein-reaches the level ofthezlower end of the tube 1186 since;a balanced condition then exists. The operator GlOSQSithe valve I70=before-removing the receptacle 190 while the valve 1-76: may also be closed to prevent liquid ttrom being forced up out of the :tube 186. In Fig.'18, I show the provisionof a stop 192 carried by thedower endof a threaded rod 195%.

This and en gages in a threaded hole formed in a lug l96:extending out from the tube 160.

A lock nut 198 serves to hold the stop :in its adjusted position. Upon loosening this lock nut, the stop 192-may :be readily set at the-desired height for engagement by a receptacle 200 wh ich'is to be filled. 7

In all=ot the forms of the invention which have been disclosed, there is-an air inlet device which permits outside air to pass through the opening into the supply receptacle and bubble up through the liquid in said receptacle in combination with a delivery pipe leading from the well with itsouter end turned downwardly and adapted to extend into the'top of a receptacle to be filled whereby the flow of liquid into the last mentioned receptacle will be automatically stopped when the level of liquid therein reaches the level 40 of the lowermost point of the air inlet device. Therefore a balanced condition will occur, the result being that no more liquid will flow into the receiving vessel, this condition being indicated to the operator by cessation of the sound of air bubbles in the supply receptacle.
